About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 737518450. Listed at 8 retailers as of November 2, 2026, with prices from $2,699 to $6,300, a $3,601 spread on the same certified stone. NZ Jewellers lists it at $6,300. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
